The terms "2D sketch" and "3D sketch" refer to different types of drawings or representations based on the number of dimensions involved. Here's a brief explanation of each:

  1. 2D Sketch:

    • A 2D sketch is a drawing or representation that exists in two dimensions: length and width. It's a flat, planar depiction of objects, typically created on a flat surface like a piece of paper or a computer screen. In a 2D sketch, objects have only height and width but no depth. Common examples of 2D sketches include floor plans, elevations, and technical drawings.
  2. 3D Sketch:

    • A 3D sketch is a drawing or representation that exists in three dimensions: length, width, and depth. It depicts objects in a way that provides a sense of their volume and spatial relationships. Unlike 2D sketches, 3D sketches convey the full three-dimensional nature of objects. 3D sketches can be created using 3D modeling software, allowing users to manipulate objects in all three dimensions.

In the context of computer-aided design (CAD) and 3D modeling, a 2D sketch is often the starting point for creating 3D models. Designers or drafters may create 2D sketches to plan or visualize a design before extruding or manipulating those sketches to generate a 3D model.

In summary, the main difference between 2D and 3D sketches is the number of dimensions they represent. 2D sketches are flat and exist in two dimensions, while 3D sketches represent objects in three dimensions, providing a more complete spatial representation.
